These are caused by a block in the epididymus , which has many tubes collecting seminal fluid from the testes. They are noticed as painless lumps behind the testes, which are usually firm but indentable masses. Epididymal cysts are benign and rarely require treatment. They are generally caused by mild trauma, often unperceived.
Any lump in the scrotum must be examined by a doctor.
If an epididymal cyst is diagnosed, it should be left alone unless large enough to cause physical inconvenience.
The homeopathic remedies Apis and Graphites, potency 30, taken twice a day for two weeks have been seen to reduce testicular cysts.
Surgical intervention should be considered only as a last resort because operations in this area may cause scarring that can block the seminal duct and lead to infertility.
